Clorazepate is excreted into breastmilk and appears to accumulate in the serum of breastfed infants. Because the half-life of clorazepate and its active metabolite are long, timing breastfeeding with respect to the dose is of little or no benefit in reducing infant exposure. Other agents may be preferred, especially while nursing a newborn or preterm infant. If clorazepate is used, monitor the infant for sedation, poor feeding and poor weight gain.
